  1. 1. Human Activity Recognition Models and Step Counter With Smartphone Sensor Data

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Josef Afreim; Simon Bossér; [2023]
    Keywords : ;

    Abstract : In this time of technology, with the availability of wearable sensors and copiousamounts of cheap data, new uses of machine learning emerge. Tasks that were previouslyheld-back by a lack of data and computation power are today more feasible and useful thanever. Human activity recognition (HAR) is one such task. READ MORE

  3. 2. Validation of a new iPhone application for measurements of wrist velocity during actual work tasks

    University essay from KTH/Ergonomi

    Author : Mohammed Abderhman Abaid; [2023]
    Keywords : Angular velocity; goniometer; inertial Measurement Unit IMU ; “ErgoHandMeter”; percentile; correlation iii; Vinkelhastighet; goniometer; IMU ; ErgoHandMeter ; percentil; korrelation;

    Abstract : The breakthrough in mobile technology and the development of smartphones, supplied with sensing devices such as Inertial Measurement Units (IMUs), has made it possible to obtain accurate and reliable data on the angular velocity for different objects. The available technical sensors for wrist movements, such as electrogoniometers, are costly, time-consuming, and need a particular computer program to be analyzed. READ MORE
